Aw, I'm getting slightly damp eyed at the thought of him being that pleased with our little parcel - especially as it was print outs off the internet, a pack of crayons my sister rescued from the skip at work and some buttons. Did Elizabeth like hers too? Pen friends would be brilliant! At least they'd stop complaining that they got no post then too. 
Are you sure about the clothes? You don't want them back to sell them or save for your sisters next one?
No help with Elizabeths paddys I'm afraid as Catherine is just as bad. Alex never stropped like she does. She had my whole family in stitches at the weekend as she did her 'Incredible Sulk' impression, gripping the edges of her highchair tray till her knuckles went white, shouting and shaking with rage while going bright green red - all because I was trying to blow her food to cool it down so she could eat it!!
Little monster got so annoyed with me on Monday because I wouldn't let her climb out and run off during her swimming lesson that she bit me! It was really hard too, the mark was still there when I went to bed that night.
She also pinches if she can't get her own way. Alex was never this bad but then i suppose as a PFB he had a lot more of my attention and I had a better chance to head the tantrums off before they got going.
I keep reminding myself that it must be very frustrating to not be able to tell anyone what you want and that she must be due a developmental leap soon so her language can catch up. It'll be better when she can talk a little better.
Right?
